  • Internal combustion engine and method for operating an internal combustion engine
    Patent number: 6619241
    Abstract: An internal combustion engine and a method for operating the multi-stroke combustion engine is disclosed. The engine is provided with individual variably controlled inlet and outlet valves in each cylinder. Operation of the engine involves controlling the inlet and outlet valves so that the opening and closing of the valves are adapted to a second stroke mode that is different from a first stroke mode in which the engine is presently running. Fuel injected into the cylinders is controlled so that it is injected prior to an expansion stroke. The transition from the first stroke mode to the second stroke mode occurs independent of the operating condition of the engine throughout the entire operating range of the engine.
